1University of Western Australia, Perth, Australia
²Inst. of Geosphere Dynamics of Russian Academy of Sciences, Moscow, Russia

The congress will be held on 27 April–2 May 2025. The EGU General Assembly 2025 (EGU25) will be a conference with a virtual component where everybody is welcome, in person or online! 

The session is NP7.1
The deadline for abstracts is 15 January 2025.

Waves in the Earth’s crust are often generated by fractures in the process of their sliding or propagation. Conversely, the waves can trigger fracture sliding or even propagation. Analysis of wave propagation and their interaction with pre-existing or emerging fractures is central to geophysics. Recently new observations and theoretical concepts were introduced pointing out to the limitations of the traditional concepts. These are:
• Multiscale nature of wave fields and fractures in geomaterials
• Rotational mechanisms of wave and fracture propagation 
• Strong rock and rock mass non-linearity (such as bilinear stress-strain curve with high modulus in compression and low in tension) and its effect on wave propagation 
• Apparent negative stiffness associated with either rotation of non-spherical constituents or fracture propagation and its effect on wave propagation
• Triggering effects and instability in geomaterials
• Active nature of geomaterials (e.g., seismic emission induced by stress and pressure wave propagation)
• Mechanics of granular material blowout by gas filtration
• Non-linear mechanics of hydraulic fracturing
• Synchronization in fracture processes including earthquakes and volcanic activity

Complex waves are now a key problem of the physical oceanography and atmosphere physics. They are called rogue or freak waves. It may be expected that similar waves are also present in non-linear solids (e.g., granular materials), which suggests the existence of new types of seismic waves. 

It is anticipated that studying these and related phenomena can lead to breakthroughs in understanding of the stress transfer and multiscale failure processes in the Earth’s crust, ocean and atmosphere and facilitate developing better prediction and monitoring methods. The session is designed as a forum for discussing these and similar topics. 

Best regards,
On behalf of the convener’s team

The 2025 International Engineering Mechanics Institute Conference will be hosted by Tsinghua University in Beijing, China from July 17-20, 2025. Ghassan Shahin (EPFL), John Rudnicki (NU), Giuseppe Buscarnera (NU), and Dawei Xue (Tongji U.) would like to invite you to contribute to the mini-symposium ADVANCES IN GEOMECHANICS AND GEOPHYSICS FOR SUB-SURFACE TECHNOLOGY AND NATURAL HAZARD (MS-20). Topics of interest include, but are not limited to:

• multiscale and multiphysics mechanics of porous rocks
• fault mechanics, fracture mechanics, and deformation banding
• field and laboratory methods
• constitutive, multiscale, and data-driven modeling

Abstract submission is now open and will remain open until February 3, 2025. Abstracts can be submitted here.

We hope you will submit an abstract to the conference and meet you in Beijing, China!

The next gathering of the European Geoscience Union – EGU 2025 (Vienna, April 27 to May 2, 2025) – will host for the fifth year the session on Nature-based and bio-based or inspired solutions for geohazard mitigation on slopes and streambanks

The objective of the session is to stimulate the interdisciplinary exchange of knowledge on nature-based (such as use of vegetation,  capillary barriers, …), bio-based (such as MICP calcite induced by microbial activities, biopolymers, …) or bio-inspired (root-shaped anchors for soil reinforcement, …)  solutions for the mitigation of risks related to hydro-geological disasters, with particular attention to landslides and erosion on slopes and streambanks.

Contributions will range from:
– experimental studies (lab and field testing or monitoring)
– numerical analyses and upscaling of results
– tools, design approaches, best practices, manuals, and guidelines
– National and European policies
– case studies and soil bioengineering applications

The session has been organized by
Vittoria Capobianco, Alessandro Fraccica, Manuela Cecconi, Zhun Mao, Anthony Leung.

Interested participants are welcome to submit an abstract within January 15, 2025 (13:00 CET).

Thank you for your support to AGERP lecture series from the past four years. At AGERP’20 AGERP’21, AGERP’22, and AGERP’23, we have more than 50 lectures and 1 panel discussion that brought together more than 60 renowned geoengineering experts and a huge audience from 131 countries through a free to access knowledge sharing platform. Apart from the generous support from the experts that appeared in the past fourth editions of, it is your participation and appreciation that largely contributed to the success of AGERP.

In the last four editions of the AGERP lecture series, we covered quite a breadth of topics related to geotechnical engineering. In the fifth edition, we intend to dive even further and deeper into some of the specialised topics in geotechnical engineering. To that end,  we are pleased to invite you to the Indo-Australian Workshop on Geotechnical Engineering, scheduled to be held from 29th November 2024. You may register for the workshop at www.age-rp.com. Program for the workshop is summarised in the Flyer (In IST and AEST).

The aim of Powders & Grains 2025 (to be held in Goa, India, during 8-12 December 2025; https://www.powdersandgrains2025.co.in/) is to share the recent advances in the broad research field of granular media and particulate suspensions. Contributions from experts around the world will cover a wide range of topics.

Powders & Grains (https://www.powdersandgrains.org/) is the premier international scientific conference held every four years in three different continents (Europe, America and Asia & Oceania) since 1989. It brings together engineers, physicists and applied mathematicians interested in the mechanics and physics of granular media and particulate suspensions. It distinguishes itself from other meetings on granular materials by (1) the mixture of disciplines, (2) the unique single-session talks, (3) the posters taking a prominent role and being displayed throughout the conference, and (4) the refereed conference papers published online before the meeting.

Dear Colleagues,

From April 14th to 17th, 2025, we are organizing an international workshop titled “International Workshop on Granular Materials & Regolith” at the University de Lorraine, Metz, France. The theme of the event will focus on: “Granular Materials Fundamentals, Applications, and Concepts for Extraterrestrial Regolith, including the Moon, Mars, and Asteroids.”

The event will bring together specialists and established researchers from academia, government agencies (including NASA, ESA, CNES) and industry. Participants will exchange and discuss ideas and topics related to regolith issues, particularly how knowledge and methods developed for granular media can help to approach extraterrestrial regolith behavior under extreme temperature, thin atmosphere, radiation, meteorite impact and other extreme environmental conditions.

The Workshop will have 10 sessions including 10 invited researchers/specialists delivering keynote presentations and 14 invited Feature presentations,18 quick-talks, and a poster session with more than 40 presentations.

We are pleased to invite you to participate in this event, and we will be grateful if you could circulate the attached flyer to those interested.

More information can be found on the workshop website at: https://regolith-metz.event.univ-lorraine.fr/ or here. We look forward to seeing you at the workshop in Metz, France. Thank you.

With all the best,

On behalf of International Organizing Committee
